application filed July M, 1919. Serial No. 310,553.

To all whom it may concern:

Be it known that we, MICHEL NADEAU and ADoLeHE Boovmn, citizens of theUnited States, residing at Auburn and, Lewlston, respectively, in thecounty of Androscoggin, State of Mame, have invented a new and usefulCheck for Looms, of which the following is a specification.

Thls invention relates to checks f r looms one of its objects being toprovide a simple and compact device constituting an etficlent check forthe shuttle of a box loom and which can be applied readily to the back 0the lay and under the shuttle box.

Another object is to provide a device of this character which can beused on any standard form of single box loom.

With the foregoing and other-objects in View, which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts which will be hereinafter morefully described and pointed out in the claims, it being understood thatvarious changes may be made in the construction and arrangement of theparts without departing from the spirit or sacrificing any of theadvantages of the invention as set forth in the claims.

In the accompanying drawings. the preferred form of the invention hasbeen shown.

In said drawings- Figure l is an elevation of the device in position.

Fig. 2 is a horizontal section through the check on the line 22, Fig. 3.

Fig. 3 is a central vertical transverse section through the device, onthe line 3-3,

ig. 4 is a plan View of the friction shoe.

Fig. 5 is a side view thereof.

Referring to the figures by character of reference, A designates aportion of the lay of a loom and B designates a shuttle box. The checkconstituting the present invention is adapted to be secured to the backof the lay and under the shuttle box and includes an attaching plate 1having a slot 2 for the reception of an attaching bolt. 3 extend fromthe plate 1 and are designed to extend under the lay, thus to hold theplate against rotation about the bolt in the slot 2. Extending along thelower edge of the plate 1 at right angles thereto and under the lay is aflange 4: provided in its free'longitudinal edge with spaced dovetailrecesses 5 adapted to receive the dovetailed. lower ends of guidefingers 6 extendl'ng downwardly from a top plate 7 on which are formedreinforcing rlbs or webs 8. s The fingers are adapted to be inserteddownwardly into the recesses 5 after which the top plate 7 and webs 8are secured to the plate 1 by screws 9 or the like inserted through theplate. The plate 1 is preferably formed wlth upper and lower openings 10separated by a bar 11 and a lug 12 extends laterally from the centralportion of this bar and under the top plate 7.

Extending through-the center portion of the flange 4 is an adjustingscrew 13 preferably provided with a lock nut 14. and bear 1ng downwardlyupon this screw is a bowed spring 15 the ends of which are slightlydownturned and which spring forms a friction shoe. The sides of thespring are extended laterally to form shoulders 16 which project betweenthe fingers 6 and under the bar 11, thereby to hold the spring againstlongitudinal displacement.

which the lug 12 projects and the walls of the recess are covered withleather or other cushioning material as shown at 19. Oppoe sitelyextended U-shaped arms project from the ends of the slide, as shown at20 and the ends of the arms lap andinterfit, as at 21, and are heldtogether by a bolt- 22. A picker arm is adapted to work within theloop-formed by the arms 20 and'when it strikes either end portion of theloop it will shift the slide 17 longitudinally until (Ime egd of therecess 18' comes against the ug 1 the pounding and the spring shoe 1'5acts to retard the movement of the slide and, consequently, the pickerarm.

By employing the lapping connected arms 20 the device can be appliedreadily to the picker arm and lay. The screw 13 allows the tension ofthe spring shoe to be adjusted as desired. 7 y

What is claimed is r--- 1. A check attachment for single box looms,including an attaching plate, a flange thereon, a lug upon the plate andoverhanging the flange, a top plate detachably fastened tothe attachingplate, guide fingers The cushioning strip 19 reduces depending from thetop plate andconnected to the flange, a-spring shoe adjustably supportedabove the flange, a slide mounted on the shoe and frictionally engagingthe top plate, said slide having a recess into which the lug extends,and a loop carried by the slide for the reception of a picker arm.

2. A check attachment for single box looms including an attaching platehavin a flange, a lug on the plate, a top plate etachably connected tothe attaching plate and flange, an adjustably supported spring shoe, aslide on the shoe and frictionally
